Application filed June 4,

This inn-:ntion relates to machines for making such conq'iosite articles as the insoles for shoes disclosed in Letters Patent of the United States No. 1,382,818, Bunkers & Bradford, June 28, 1921. In these insoles there are combined a sheet of body-material, which may be leather or a leathensubstitute, and. a. sheet ot canvas or other fabric, in which a sewing rib is molded. In manufacturing such insoles, it is necessary to first form the, rib in the fabric, and then assemble the ribbed sheet and the body-sheet, securing them to each other. The present in vention has ai'nong its objects the provision of a machine which while relatively inexpensive, especially as to the outlay necessary for the forming dies, and occupying but small space.v will produce such insoles rapidly and efficiently.

In the attainment of these objects, there are combined, in the illustrated machine, a carrier having a. plurality of work-supporting sections and movable to dillierent oper ating positions,and a plurality 0t opera-ting mechanisn'ls, one of which is arranged to act upon plural cai.'riersections, while the other mechanisms act upon particular sections only. By making the mechanism common to plural carrier-sections that which etlects the forming of the material, as the molding ot the sewing rib and the pressing together of: the layers, the costof the apparatus may be reduced, since there are required itewer dies, which dies are in comparatively large sets corresponding to different sizes of insoles. l eeding mechanisms, which may sup ply, respectively, the body-material of an insole and the fabric layeryact only upon particular sections Q?! the carrier. The preferred organization involves a carrier, shown as alBClIJTOCt'ltOly plate havii'ig two sections, which may be presented simultaneously at two of three successive positions, the outer positions havingmechanisms which supply the two kinds of wink-pieces to respective carrienstections. wnile the mechanism at the intermed ate position applies pressure to' the deli "cred pieces. The movable *arrierportion 0? such an organizatiim may be light, with small imartia, and conscquei'itly may be operated rapidly, with the expenditure of little power. Registration between the carrier-elementsand those at the operat ing positions may be readily effected and 1927. Serial No. 196,580,

with accuracy at the two extremes of travel. The operating meehanisn'is may be in pairs at opposite sides of the carrier, the rib-moldingprojection with which a section of the carrier is provided extending between the opposite faces and serving for both. In this way, two insoles, a. right and a left, may be produced at the same time with an economy in the production of the diesl More over, the pressure applied to the carrier by the mechanisms in duplicate is balanced. Each section best so mounted that its operating surface or surfaces lie generally in substantially vertical planespto which the feedingmechanisms delivelgand means is furnished, as at the upper edges of the surfaces. for holding the supplied pieces. This holding or retaining means is shown, in one instance, as furnished by suction devices, and in another by spurs, the former well lending itself to the'retention of the fabric, while the latter is effective in connection with the leather or other body-material. lVith the mechanism at one of the positions, as that which iteedsthe hody-niaterial and to which is brought a completed insole, maybe associateiil a delivering mechanism, which removes the work. "from the carrier. WVhen two insoles are formed at'opposite sides of the carrier, this mechanism grasps and delivers these simultaneously. In the present embodiment of the invention, the ,pressure mechanism, which is identified with a particular position includes a die, grooved and complemental to the rib'torming projection upon the die-section of the carrier, which die has means, as, for example, its groove, for

retaining upon it the formed insole-piece,

during the travel of the associated die. To tree the work from this retaining means, there is provided some such means as air under pressure.

To deliver the insole-pieces to 21v substantially vertical operating 'tace'of the carrier or other support, there is present, as another feature of the invention, means arranged to receive the pioces in a substantially horizontal position, and elevate and apply them to the operating taco. To the elevating member in its horizontal position, the pieces may be transferred from a magazine, while at: the operating tace,it presses said pieces against the retaining device with which the carrier is provided. lVhen the earner 1s double, with two operating faces at opposite sides of a reeiprocator plate, as alread pointed out. the ele'ating mums is correspondingly duplicated. receiving the pieces through transferring mechanisms trom a magazine situated at each side of the path of the -arrier.

Upon a l time F are supported the various elements of the machine. the principal groups of which turnish the rarrving me hanism A. h which the work is transferred from one operating position to another and which shares in the insole-forming etl'ectn: the feeding mechanism ll. hr which a layer fabric is supplied to the carrier for the operation upon it; the leather-feeding mechanism (3 similarly i-uppl cing the carrier: the prcs nrc mechanism I) cllceting' the l'ormation ol' the worh-pim-cs: and the in- .--ole-:lelivering mechanism I) for removing the completed work l'rom the carrier. .iilnlt: two insoles. a right and a left. are preteralilv produced simultaneously. the carrying mechanism has opposite receiving and formand the meclnmism. l.

about the associated sleeve.

34, against which the pieces may be pressed and held for the operation upon them. The spurs prefe. ably have. a slight upward inclination, so they resist downward displacement of the pieces which they support, yet permit their free removal in an up Ward direction. The carrier A may be readil removed from its guiding ways and repaced by another bearing a projection adapted to mold the rib in an insole of another size.

To reciprocate the carrier so that the sections 18 and 20shall alternately occupy positions to co-operate, respectively, with the fabric-feeding mechanism 1?) and the pressure mechanism D, and then with the pres sure mechanism D and the leather-feeding mechanism C, together with the delivering mechanism E, and to give the proper dwell at each position for the various operations to be performed, it is connected to cam mechanism. Joined to the motor 32 by reducing gearing 36 is a main cam-shaft -38 journaled horizontally near the lower portion of the frame and extending longitudb nally thereof. This shaft. in addition to its can1-actuating function, operates a group of rotary valves, one of which, designated as 39, governs the suction applied to the vacuum nozzles 26 through the pipe 28, as already indicated. Fast. upon the shaft 38 is a double clutch member 40 (Figs. 4 and 18), at the opposite sides ofwhich sleeves 42 and 44 are mounted to rotate about the shaft 38, each sleeve having lixed to it a series of cams. Secured to each slceveis a clutch member 46, which may carry sliding blocks 48 movable into and out of engagement with lugs upon the corresponding face of the clutch member 40 to produce rotation of the associated sleeve, or to allow it to rest while the companion sleeve is rotated. To actuate the blocks of each member 46, a cam-ring 50 (Fig. 17) is mounted to oscillate beside it A detent movable to engage projections 54 from the periphery of each member 46 stops the latter in a predetermined position. .iournaled in the frame, beside the shaft 38, is a shaft 56 (Fig. 18), rotated. through reducing gearin;- 58 from said shaft Fixed to the shaft 56 are two cams 60, 60, one for actuating the rings 50v and the detents 52 of each of the. clutch members 46, and arranged to produce rotation of the cam-sleeves 42 and 44 at the correct time in the cycle of the machine. Each of the cains66 oscillates a bell-crank lever 62 fulcrumed upon a bracket 64 at the rear of the frame. Each lever 62 is joined by a link 66 to the corresponding cam-ring, the connection being continued by a link 58 to a toggle-lever 70, which actuates the detent 52. -This clutch and its controlling mechanisn'i are substantially as described in the application filed in the United StatesPatent Office April- 20, 1.922, in the name of Edna A. Perry, executrix of the will of Frederick H. Perry, deceased, this hearing the Serial No. 555,774. A cam 72 upon thesleeve 42 (Figs. 9 and 18) acts upon a lever 74 carrying a roll held against lhe'cam by a spring 7 6. A link 77 (Fig. 4) is articulated to the lever 74 and to a hellcrank lever '78 linked at 80 to a lever 82 joined by a link 84 to the carrier 1L.

The canvas-feeding mechanisms B, B appear in Figs. 1, 4, 13, 14 and 15. They generally rescmblethc corresponding mechanism in an application tiled in the United States Patent Oiiice April 13, 1925, in the name of Eric A, Holmgren and bearing the Serial No. 22,624. Considering one of these, its companion being identical, mounted up on a bracket 88 projecting from the main frame is a skeleton magazine-frame 90. The vertical elements of the magazine-frame may be supported for adjustment toward and from each other, as is indicated at 92, so they may be varied in position to adapt them to receive pieces of different sizes. :leneath the magaziine-frame, and extending: axially thereof. a vertical guide-rod 94 surrounded by a sleeve 96, which carries at its upper extremity a platform 98 for the support of a stack of the canvas pieces 3) tobe fed. An arm 100 projects from the bottom of the sleeve. and is guided by a secondvertical rod 102. passing about astepped sheave 106 and having at its opposite extremity a weight 108, which substantially counterbalances the plat form and the supported stackof work-pieces. To raise the platform and stack gradually as the pieces are fed from it one by one, the sheave is rotated in successive steps by en- ,n'ager'ient with ratchet-teeth 110, which it carries, of a pawl 112 pivoted upon anarin 114 fixed to a shaft 116 extending adjacent to both feeding mechanisms. The shaft 116 has an arm 118 (Fig. 1.) joined by a link 120 to a lever 122 fulcrumed below the shaft I 38 (Fig. 13). Upon the sleeve 44 (Fig. 18) is a disk 124, in one face of which is a came roove 126. v A bell-crank lever 128 has at the end of one arm a roll lying within the groove. while the other arm is united by a link 1310 to the lever 122. For each oscillat on of the lever 122 by the cam, the ratchet To the arm is connected a cordlO-i mechanism rotates the sheave to raise the f plat'l orl'n and thus the top ofthe stack ofv upper extremity of a carrier-lever 134 pivoted on the outer end of one of the previously mentioned levers 122. there being one ot-lhese heads for each canvas-feeding mechanism It. The same movementby the cam-groove 126 which has been already described as operating the platform-elevating ratchet mechanism lowers and raises the head 132. imparting to it a vertical component of the movement which causes it to enter the magazine. engage the top piece therein. and transfer it to an elevating leaf or support 136. by which the final delivery to the carrier-section 18 is made. The horizontal componentot this transferring movement :is derived from a cam-groove 138 in the opposite side of the disk 124: from the groove 126. A. lever 140, tnlcrumed about the same center as the levers 122. 122. has a .roll operating in the groove 138 and is linked at 11-2 to one of the carrier-levers 131 for the suction-head and at 144: to a lever 1-l-ll. which. at 148. is joined to the lever of the other suction-head. The canvas-retaining suction at the heads is created from the pump 30 through a pipe 150 including flexible sections. and is correctly timed to seize and release the pieces by a rotary valve 152 actuated by'the shatt 38.

The leaves 136. already referred to as receiving the pieces of canvas from the transterring devices. are shown as normally lying in horizontal position adjacent to the carrieusection 18 when this is at the canvasreeeiving position. Each leaf is pivoted upon brackets 154- rising from a supporting rod 156 extending transversely of the main Frame (Figs. 4 and A cleat 158 along its inner edge serves as a rest for the deposited piece. While the leaf is being elevated to a vertical position. presenting the canvas to the retaining action of the nozzles 26. This movement of the leaves is effected by a ram 160 upon the sleeve 44, it connnunicating movement to a lever 162, which. through a link lti-l. oscillates an arm nae pivoted at 168. This arm is linked at 170 to one of the elevating leaves. and carries a gear-segment 17;. which actuates the companion arm 166 and its leal".

The leather-feeding mechanisms C are mostcomplctcly illustrated in Figs. 1. 4. 6. T and 113. Each has a vertical magazine 180. in the form of a skeleton-frame. arranged for convenient removal "from the main frame so the size of the pieces (I operated upon and their container may readily be changed. These magazines are situated opposite the section 20 of the carrier when this is in its leather-receiving position. Against the outer edge of the bottom piece in each of the magazines moves a feeding slide 182 mounted to reciprocate in ways in a bracket 18 1 secured to the side of the frame F. The movement; is effected from a cam-groove 186 new/.051

(Figs. 16 and 18) in a disk 1H1; fast upon the sleeve 42. This groove receives a roll upon a lever 1.) joined by a link 1972 to a lever H arranged to rock about the sleeve 4-2. To the opposite extremities of the lever lttt and to levers lllll. 11 1' are articulated links 198. 198. and the upper endof the levers 1213 are linked at 2th) to the respective slides 182. As each slide travels l'omvard from the position illustrated in Fig. 16. it; i'orces l'rom the bottom ol' the lll't-'llt)ll illljj stack. through an opening in the inner side ot the magazine. a l ather piece 0. delivering this upon the horizontal surface of a cleatcd leat 2H2. 'lhese leaves. which ele vate the pieces (7 against the opposite l'accs oi the carrier-section 20. may he in every respect the same as the leaves liltl. which act upon the canvas pieces. and are shown as being operated in the same manner. their tll'llls 2% being oscillated through a link 2 16. lever illltl and cam-groove 211 in the disk 1%. .ln their vertical position. the leave 202 force the pieces against the spurs ll. which. as the leaves descend to their normal position. retain said pieces upon the section 2H for the. operation upon them.

The pressure mechanisms 1) l igs. l. t. t ta and ]l cooperate tirst with the section 18 of the carrier A to produce the sewing ribs (I upon the coated canvas pieces. and then with, the section to cause the adhesion of the t'ormed canvas. which has been re= tained upon the pressure-sorl'aces ol' the mechanims l). to leather pieces. illoun i to slide. upon the rods 10. at each side of the guide member 12, is a cro;--'-head :20. upon which is secured. to permit change of size. a plate 222 (Figs. 11 and 12) carrying a die 224. which has a groove 226 eomplemcntal to and arranged to regi ter with the projcction 22 of the die-section 18 ot the carrier. Upon the rods 10. outside each cross-head. is an abutment-block 228. yieldahle against springs 230 surrounding the rod and backed by nuts 232 threaded upon the outer portiom ol the rods. Variation in the position ol these nuts permits a change in the normal relation of the operating surlace ol' the die 22 to the opposed i'aces ol thc carrier-swtions. Joining the crossdiead and block is a. toggle 234. connected l a link 2 36 to a lever 238 tnlcrumed upon the rod 15a. The opposite extremity of the lever 23% is similarly connected to the toggle ol' the associated cross-head. Depending from the lever 238 are arms 210 having rolls contacting with opposite port-ions ot the peripheries of like cams 24-2. 2-12 secured to the sleeve -l-!. These cams provide for the movement oi" the dies 221-. 221- iuto simultaneous o-opci'zltion with the sections 18 ot the carrier and then With the sections 20. with the appropriate dwell to produce the rib-molding and assembling effects, and with intermediate petill Ill)

(ill

riods of rest, during which the pressure-dies are separated from the carrier and other operations take place. To facilitate both the molding and assembling actions of the dies 224, each may be PIOVltlUCl with heating means, indicated in Figs. 10 and i2 as consisting of electric units 2 14 rel/l1 the face of the head 220 behind the die plalc 222, the units receiving current through conductors 246. .To free the sewing ri'b a from the groove 226, so the completed insole may be removed more readily from the die 224 by the carrier-section 20 after the canvas and leather pieces have been united, air-pressure is introduced through passages 24:8 opening through the operating face of each die and extending through its mounting upon the cross-head. From these passages, pipes 250, including flexible sections, communicate with the outgoing side of the pump 30. A rotary valve 252, included in the main run of the pipes 250 and actuated by the shaft-38, controls the work-ejecting air-blast.

Upon movement or the section 20 to the leather-receiving position, it carries upon its opposite faces two completed insoles, which must be removed before there are applied to it the pieces 0 which are to be included .in thesuccecding pair of insoles. Referring to Figs. 1, 4, 5 and 9, there is pivoted upon the main frame, by means of a transversely extending shaft 258, an arm 260 of the d-c livering mechanism l At its free end, this arm carries a plunger 262 urged downwardiy, when the work-engaging position considered, by a spring The extent of this moven'ient may be limited by a collar 266 threai'led upon the upper end of the plunger and contacting with the arm, as is shown in the dotted-lino position of the mechanism in Fig. 4. A reduced stein 268 upon the lunger is so situated that it may be swung in the inoven'ient of the arm into a cut-away portion 270 at the upper edge of the carriersection 20. Fron'i the opposite sides of the stem 268 project lugs 2T2, upon which are pivoted jaws 2T l-,-with their grasping portions opposite the end of the stem. Links 276 oiu the jaws to the end oi the lever 2G0, and cans-fie the spring 26-41 to force said jaws away from the end, of thcsteni 268. They may, however, be held temporarily in grasping relation to the stein by a latch 2T8 pivoted upon the arm and forced by a spring 280 toward the plung *1, so it may be engaged by the inner c of the collar 266. The latch may be disengaged from the col.- lur, to allow the jaws to retreat from the stem, by a toggle-conneclion between the latch and the pimt-sluift 258 of the arm. lVhen the collar and. latchare in cngageinci'it, the toggle is .ight. This is shown in full lines in Fig. 4:. To break the toggle,

as p-pears in dotted lines in Fig. 4-, and the y withdraw the latch from the collar,

said toggle is brought into contact with a relatively fixed member, here shown as adjustable, and furnished by a. screw 284 threaded through a frame-projection. To

arm. 260 is lowered until the stem 268 enters the depression 270 in the carrier-section and contacts with the edge of said section. This raises the plunger 262, and, through the connection of the jaws to the arm by the links 276, compels said jaws to close upon the opposite portions of the insoles, which "rise slightly above the carrier, as is best shown in Fig. 5. lVhen the work is thus engaged, the collar 266 upon the plunger has been raised to a point allowing the latch 278 to be forced;beneath it by its spring. 280. With the two insoles thus grasped, the arm 260 is swung outwardly, drawing said insoles clear of the carrier, the upward incline of the spins 3a facilitating the removal.

When the mechanism E arrives outside the frame, the toggle 282 strikes the contact member 28-l, withdrawing the latch 278 from the collar. The spring 264 thereupon forces the stem 268 of theplunger away from the arm, thus separating the jaws by the action of the links 27 6 and releasing the soles, which may be deposited in a receptacle.

N ow outlining the general operation of the machine, it will be assumed that the carrier A 1s at the right, as viewed in Fig. 1 of the drawings, this positioning the rib forming section 18 in co-operation with the canvas-feeding mechanisms B, B, while the section 20 is a-lined with the pressure mechanisms D, D. A cycle Wlll be traced, begin- 'ning with the delivery to the carrier of the canvas pieces 5. The actions at this time occurring in connection with the section 20 and performed upon a preceding sole Will be disregarded. .With the'carrier in the relation just indicated, the leaves 136, each of which already bears a piece oof canvas, are. raised bythe elevating mechanism into a vertical position, bringing the pieces against the die-projcctions 22. Under the control of the valve 39, the pump 30is now drawing air through thenozzles 26, so the pieces 6 are held against the sections 18 while the leaves 136 resume their original horizontal positions. WVith the received pieces I), the carrier travels to the left (Fig. 1), while the suction-heads 132, in which the vacuum is controlled by the valve 1T2, prepare for the delivery to the leaves of other pieces of canvas. The carrier having, completed its movement, with the section 18 in registration with the pressure mechanisms D, D, the cross-heads 220 are moved toward the carrier, so that the die-recesses 226, in co-operation with the projections :22, form sewing ribs a in the canvas pieces, heat generated by the electric units 2&4 assisting .in rendering these ribs more rigid. The nozzles 26 expand laterally under the pressure between the dies. The delivery of the canvas pieces to the leaves 1536 continues, while the leaves 202 at the leather-feeding mechanisms U, C elevate previmisly supplied pieces 0 against the opposite surfaces of the carrier-section 20, where they are impaled upon and re tained by the spurs 3. The cross-heads of the pressure mechanisms have retreated, carrying with them the formed pieces of canvas retained by the engagement of their ribs with the diea'eccsscs 226. The carrier starts back to the right, the suction-heads returning from their ('lelivta'y to the leaves .136, and the teed-slides 1,82 forcing from the magazines leather pieces (2 upon the now open leaves 202. Attaining its righthand position, the carrier again presents its section 18 to the canvas-l'ceding mechanisms B, ll, and its assembling section, 20 to the pressure mechanisms l), l). The cross-heads of the latter, carrying the molded canvas pieces, are ad armed to force latex-coated surfaces of said pieces against the leather pieces 0 held upon the spurs 34. The pressure between the opposed die members, aided by the heat applied by the electric units, produces a firm adhesion of the two pieces, completing the formation of the pair of insoles. \Vhcn the cross-heads are witlnlrawn, the insoles are prevented trom being carried with them and are compelled to remain on the carriersection 20 by the blast of air delivered through the die-passages 248 and governed by the valve 252. During the assembling operations at section 20, a supply of the canvas pieces is occurring at section 18, as already described. At the leatherd eeding mechanisms C, C, the leaves 202 are horizontal, and the slides 182 have advanced and delivered the pieces to them. The carrier is shifted to the left, and the delivery mechanism E descends, and, by contact of its stem 268 with the edge of the cut-away portion of the carrier-section 20, closes its jaws uponthe upwardly projecting edges of the two insoles, and then draws these from the spurs, carrying them outside the trame. Here, contact with the member QSl opens the jaws, and the completed insoles are released. After the removal of the work, the lca'vcs 202, with the leather pieces 0 upon them. are elevated to apply these pieces to the sections 20. The slides 182 have resumed their normal positions ready for the succeeding feeding operation. Canvas pieces 0 are being supplied to the leaves 136 ready for the next movement of the carrier to the right.
